Safety Evaluation of Bioactive Glass Based Bone Cement Combined With Ultrasound in Implantation for Metastatic Bone Tumors

This study is evaluating the safety of using bioactive glass-containing bone cement combined with ultrasound during surgery for patients with metastatic bone tumors. We aim to see if this treatment can be safely applied to stabilize the bone and reduce pain, without causing unexpected side effects. All participants will receive standard care plus the study treatment, and we will closely monitor them during and after the procedure to check for any safety concerns.
